Discovered my 04 Yamaha F225 with 1200 hours Lower unit leaking oil at the perfect time as Fishing season is now starting to kick off. Went to my local shop to pick up some more fluid and they are booked till Oct! Is my season over or can I just keep filling the LU fluid and run till mechanic can fix. Shop said its not good cause the pressure built will just push the fluid out and it is unkown when it will let go. Sorry I am not familiar with outboards but when you get leaky tranny in a car its not the end of the world just stay on top of fluid loss. Hoping this is the same and you experienced guys chime in. Im ready for the snide comments coming. Will Look into how to vids to do all the seals myself cause I'd be crushed if my season is over. Same time I dont want to grenade anything.
